Exhaust Manifold Gasket Set for OE-Style Sealing

Victor Reinz 11-10623-01 is an exhaust manifold gasket set built for high-heat sealing at the exhaust manifold. It uses graphite and metal construction with a one-piece configuration and a 0.050 thickness to support a tight seal on older Oldsmobile V8 applications and other listed vehicles.

Compatible with 1965-1974 Oldsmobile 98, 1971-1974 Oldsmobile Custom Cruiser, 1970-1974 Oldsmobile Cutlass, 1965-1968 Oldsmobile Cutlass, 1971-1974 Oldsmobile Cutlass Supreme, 1965-1974 Oldsmobile Delta 88, 1966-1974 Oldsmobile Toronado, and 1965-1966 Oldsmobile Starfire.

• Graphite and metal sealing materials for exhaust manifold heat exposure
• One-piece configuration for a direct manifold gasket layout
• 0.050 thickness for OE-style sealing dimensions
• 5 bolt hole quantity for the listed manifold pattern
• Cross-reference part numbers include MAHLE MS15141 and interchange numbers MS19043, MS90078

Detailed Product Overview

Victor Reinz 11-10623-01 reflects the brand’s OE supply background and is engineered to meet original-equipment specifications across a wide range of engine designs. For Oldsmobile 98, Delta 88, Cutlass, Cutlass Supreme, Toronado, Custom Cruiser, and Starfire applications, this gasket set addresses the sealing demands created by exhaust heat and repeated thermal cycling. The graphite and metal construction helps maintain a stable seal at the manifold interface, while the one-piece format supports consistent fitment on the listed vehicles.

This part cross-references MAHLE MS15141 for the same application.

Common Exhaust Gasket Issues

• Exhaust leaks at the manifold-to-cylinder-head sealing surface
• Ticking or puffing noises from a leaking manifold gasket
• Loss of exhaust sealing after heat cycling and age
• Visible soot around the manifold flange area
• Failed sealing on restored or maintained Oldsmobile exhaust systems

Installation Notes and Tips

Inspect the manifold and cylinder-head sealing surfaces before installation. Remove carbon buildup, corrosion, and old gasket material so the new gasket can seat evenly. Verify the bolt-hole pattern and manifold alignment before final tightening, and follow the vehicle service manual for torque sequence and specifications.

Quality Assurance

Victor Reinz has a long history of supplying exhaust manifold gaskets to original equipment vehicle manufacturers, and this part is built to OE specifications for the listed applications. That makes 11-10623-01 a practical choice for maintaining proper exhaust sealing on classic Oldsmobile platforms.
